PI6C48535-11CLIEX

Clock Buffers, Drivers Overview

The PI6C48535-11CLIEX is a 4-output LVPECL fanout buffer with an embedded oscillator, manufactured by Diodes Incorporated. It supports output frequencies up to 266 MHz and features ultra-low additive phase jitter of less than 0.03 ps (typical). The device operates on a 2.5V or 3.3V power supply with a maximum current draw of 85 mA. It provides low propagation delay (typical < 1.5 ns) and includes two selectable inputs: REF_IN and XTAL_IN. Packaged in a 20-contact TSSOP, it supports industrial temperature ranges from -40°C to +85°C.
